The death day banquet

The 'deathday' is not a novel concept in the Orient, where it's familiar from
Buddhism. The Chinese and Taiwanese translators conveniently make use of the
Buddhist words 忌辰jìchén
and 忌日jìrì,
which literally mean 'day/occasion of abstinence'. The two words refer to the
traditional practice of refraining from alcohol or pleasure on the anniversary
(monthly or annual) of the death of an elder or respected person such as a parent.

The Japanese are also familiar with the concept of a 'deathday'. Japanese has
several terms for this, including the two Chinese terms above (忌辰kishin and 忌日kijitsu / kinichi)
as well as the term 命日meinichi. In Japan, Buddhist services are held every seven days after a person's death. Monthly anniversaries are known as 月命日tsuki meinichi, the annual anniversary is known as 祥月命日shōtsuki meinichi, or 命日 meinichi for short.

But the Japanese translator
avoids the traditional Buddhist terms -- maybe she felt the solemn overtones
didn't fit in with the idea of holding a party! Instead, she follows the English
example, making up an entirely new word, 絶命日zetsumei-bi ('death-day'), the opposite of 誕生日tanjō-bi ('birth-day'). 絶命zetsumei is not the common word for 'death'; it means 'the end of life'.

The Vietnamese translation uses a completely literal translation
of the English: 'death + day + banquet' (in reverse order to fit Vietnamese
grammar), although Vietnamese, like Chinese and Japanese has expressions
meaning 'death anniversary': ngày giỗ or
bữa giỗ. The banquet for a death day anniversary, at which special foods may be eaten, is called đám giỗ.
